Unplugged refrigerator. Took cover off the back inside compartment in the freezer side and used hair dryer on hot to defrost the frozen coil. Once defrosted, unclipped Defrost Limiter Thermostat from top of coil, cut wires, stripped wires back less than 1/2 in., did the same to the wires on the new Defrost Limiter Thermostat, easily matching colored wires together and used appropriate wire connectors and covering with electrical tape. Clipped Defrost Limiter Thermostat back on. Put cover back on, plugged refrigerator back in and it has functioned properly since.

My sensors were the old style that are known to be bad. So i replaced all of them, but it was still freezing the bottom on both sides. So i dug further and found that the condenser fan wasn't working so i replaced it and it's been working perfectly ever since.

I went to website, entered model, went to diagram and there it was. The part was received promptly and was well packed and padded. I emptied the bin, placed entire assembly on work bench, carefully disassembled, installed new part and I am about ready to dispense a glasss of cubes for an adult beverage. Total time about 15 minutes. Just be organized and take a photo before disassembly if you think you might need it.

I researched on AppliancePartsPros.com and thought the problem could be the Ice Dispenser Solenoid. I replaced the solenoid, and also replaced the ice door assembly, ice door recess crank, and ice door recess spring. All together parts costed about $45, and bingo, problem solved! AppliancePartsPros had several videos on the subject how to reapir/replace, and those were immensely helpful. I am not at all mechanically inclined person, but those videos made it so much simpler for me to do it.
I did research the prices of the parts in other places, this place is the cheapest I found. The shipment came very quick and in perfect condition. The parts were original GE parts in original GE packaging.
